@brief Structure to describe a SPI flash chip connected to the system.

Structure must be initialized before use (passed to esp_flash_init()). It’s in the public header because some instances should be allocated statically in the startup code. May be updated according to hardware version and new flash chip feature requirements, shouldn’t be treated as public API.

For advanced developers, you may replace some of them with your implementations at your own risk.

Fields

host: *mut spi_flash_host_inst_t

< Pointer to hardware-specific “host_driver” structure. Must be initialized before used.

chip_drv: *const spi_flash_chip_t

< Pointer to chip-model-specific “adapter” structure. If NULL, will be detected during initialisation.

os_func: *const esp_flash_os_functions_t

< Pointer to os-specific hook structure. Call esp_flash_init_os_functions() to setup this field, after the host is properly initialized.

os_func_data: *mut c_void

< Pointer to argument for os-specific hooks. Left NULL and will be initialized with os_func.

read_mode: u32

< Configured SPI flash read mode. Set before esp_flash_init is called.

size: u32

< Size of SPI flash in bytes. If 0, size will be detected during initialisation. Note: this stands for the size in the binary image header. If you want to get the flash physical size, please call esp_flash_get_physical_size.

chip_id: u32

< Detected chip id.

_bitfield_align_1: [u32; 0]

_bitfield_1: __BindgenBitfieldUnit<[u8; 4]>
